CHANNEL-OVEN, DRYING-OVEN, OR THE LIKE."

Specz'ification of Letters Patent. Patented 64 31;, 23, 1917,

Application filed December 21, 1915. Serial No. 68,105.

To all whom it may concern: 1 Be it known that I, I-IANs IsAKFnRDI- NAND STRANDH, manager, a subject of the King of Sweden, residing at Forserum, Sweden, have invented certain new and useful Improvements in Channel-Ovens, Drying-Ovens, or the like, of which the following is a specification. In coolers or so-called channel ovens for bottles and other glass wares there are generally used plates or boards, on which the ready-made hot glass wares are placed and transported through the stove heated to a certain degree in order to be subjected to a successive cooling. Exceptionally sheet-iron wagons having flanged wheels are used. In either case the hot glass wares are put on the plates through an inlet at one longitudinal side of the channel cooler.

The'arrangement referring tothe present invention allows the inserting of the glass wares manually or by means of an automatic transporting device directly through an in let of the fore-wall of the cooling race.

The invention is essentially characterized by thefact that the boards for transporting the glasswares in the stove are provided with long rollers stretching in the transversal or the longitudinal direction of the wagon and that at the two ends of the stove or only at one of them a race is arranged, running perpendicularly to the cooling channel, said race also consisting of rollers or essentially of rollers for the purpose of getting only rolling friction between the board and its bed not only on moving the boards at the race in the channel and at the said rolling race, but also at every monient of the transition between the rolling race in the channel on one hand and the race outside the channel on theother hand. No special lifting arrangements or the like for making the moving of the boards easy are thus necessary. y i f Two embodiments of an arrangement according to the present invention are show in the annexed drawings. a

Figure 1 shows one embodiment in plan elevation. Fig. 2 is a section on a larger scale on the line AB of Fig. 1. Fig. 3 shows the other embodiment in plan elevation. Fig. 4 is a section on they line CD of Fig. 3. Fig. 5 shows in end view the board shown in Fig. 4.

According to the embodiment shown in sland :2 t e boards are. p o ided with rollers 1 stretching in their longitudinal direction. 4 a

, Each boardisprovidediwith four rollers arranged by two and two, whereat the rollers of each pair collineate with each other.

The rollers are of such a length as to ocboard, said guide also suitably forming a support of said bearings andembracing a rail 3 stretching along the center of the channel and thereby guiding the board during its transport in the channel. The rollers 1 rest on rails astretching at the two sides of this rail 3 andparallel-to the-same in the channel. At the outside of the stove a similar rail system 5, 6 is arranged. The empty boards run from the rails 6 onto the rolling race, arranged at the end of ,the stove and stretching transversely in relation to the rails 3, 4L, 5, 6 througha lateral inlet 8 .of the stove wall and situated half inside the stoveand half outside the stove as inclicated in Fig. 1. From the outer part of the rolling race 7 the board'is inserted into the stove pposite to -the inlet of the end wall of the stove, through which the glass wares are to be' inserted, From its position at the inner part of" the rolling racethe board is i the sides of the channel and driven toand back, said bars having pawls12 catching into racks on the wagons.

One of the particular features of the present invention is the transfer roller-races for receiving the rollers on'the boards and'thus realizing an easy and comfortable transport of the boards into the stove and out of it, so that an entire rolling effect may be produced not only when transporting the boards on the race in the channel and the race parallel .to the former outside the channel and the transition races between said channels but also at every moment of the tran- T'- sition between two races that is to say at ery m use m men there w ll. be produced.

only rolling friction between the boards and, their bed. If for instance the race of the channel and the race parallel to it outside the channel as well as the transition races at the ends only consisted in rollers but on the contrary the plates for the glass wares had no rollers, the transport of a plate from the outer race (5, 6) to the transit-ion race 7 would be performed only at utmost dithculty and a transport of the plate from the race 7 to the race 3, 4. in the channel would hardly be possible, the temperature of the stove amounting to 600 C. causing an excessive friction. It should be observed, that the weight of a charged plate is about 500 kgs. and that by transporting such a charge mainly by sliding that is to say practically without rolling effect (which would be the case during certain moments of the transition between the outer race and the end race respectively between the end race and the inner race) a considerable power is of course necessary. As will be clearly seen, this inconvenience is entirely eliminated by the present arrangement. In this arrangement only rolling eifect will prevail during each moment of the transition between the end race on one hand and the inner race or the outer on the other hand.

When a wagon is transported from the rails 5, 6 to the rolling race 7 the rollers of the wagon will roll only on the rails at first and then at the rollers 7 1) parallel thereto. The wagon having occupied its proper position on the rolling race the roll ers of the latter will operate while the rollers of the wagon, so to say operate as rails.

According to the embodiment shown in Figs. 35 the boards are provided with lateral rollers 32, three on each board. The boards rest by way of these rollers on track wheels 13, attached to axes 14: rotatably supported in the stove wall. The diameter of the rollers 32 is measured in such a manner, that the rollers fit rather precisely in the track of the wheels.

By this the boards get a straightlined guiding during their insertion and there will be obtained the friction between the track wheels and the rollers necessary for driving the boards forth.

Along the entire channel such. aXes 14: having track wheels 13 are arranged thereby forming a race for the boards. A similar race is arranged at the outside of the stove together with transition races as in the former embodiment arranged at the ends of the stove to allow the boards to be easily brought into, through and out of the stove by a perpetual circulation.

According to Fig. 3 the transition race consists in two pairs of rollers 15, 16 parallelly arranged to the axes 14, of which one pair 15 is arranged in the stove channel, the other 16 outside ofjit. 'The rollers are almost as. long as the channel is broad and the rollers. of one pair are placed opposite to the rollers of the other pair. Between the two pairs of rollers that is to say in the lateral inlet 17 of the stove wall two rail pieces 18 are placed forming a bridge between the two pairs of rollers thus forming a contin-ua l transition race for transporting the boards into the stove from the race outside the stove.

The axes 1st of the track wheels 13 by the rotation of which the boards resting thereon are carried forward, are suitably driven, in a manner known by itself, by means of a system of axis 19 arranged along the outside of the stove, said axis communicatlng with the axes 14 by means of worm gear or cog wheels. 7

Through the inlet 20 of one end wall of the stove the glass wares are inserted on a fixed plate 21, under which the boards enter from the-outer race. The hot bottles placed on this plate are seized by means of pliers inserted through the inlets 22 and are placed by rows en tee underlying board successively to the inserting of the bottles.
